Overview
The LM393FVJ-E2 is a dual analog comparator manufactured by ROHM Semiconductor, designed for general-purpose applications. It features an open collector output and supports a wide operating supply voltage range from 3 V to 32 V. The device operates with a typical supply current of 600 uA and provides an output current capability of 16 mA per channel. Key electrical parameters include a maximum input offset voltage of 4.5 mV, a response time of 1 us, and an input bias current of 250 nA. It is housed in an 8-pin TSSOP-B-8 surface-mount package and functions within a temperature range of -40 C to +85 C.
Feature Summary
- Ground-sensed input and output capability allows signal referencing to the negative power rail.
- Open collector output structure facilitates wired-OR connections and compatibility with various logic families.
- Low power consumption design ensures efficient operation in battery-powered or energy-sensitive systems.
Applications
- General purpose voltage monitoring circuits
- Over-voltage and under-voltage protection schemes
- Threshold detection in industrial control systems
Procurement Notes
Verify the specific ordering suffix and package variant against the latest manufacturer datasheet before procurement. Confirm that the component status aligns with project requirements, as availability may vary. Ensure compliance with RoHS directives and check for any recent lifecycle changes such as NRND status. Validate pinout compatibility if replacing existing designs.
Selection Notes
Select this component when ground-referenced inputs are required alongside a wide supply voltage range. Consider the open collector output for flexible interfacing needs. Evaluate the 1 us response time against system speed requirements. Verify thermal performance within the specified operating temperature range for the intended application environment.
Part Context
This part belongs to the LM393 series of dual comparators produced by ROHM Semiconductor. It shares functional similarities with other industry-standard dual comparators but offers specific packaging and electrical characteristics tailored for surface-mount assembly. The FVJ suffix indicates the TSSOP-8 package type.
Replacement Considerations
Direct substitutes may include other dual ground-sense comparators with similar pinouts and electrical specifications. Verify pin compatibility and output drive capabilities before substitution. Cross-reference with ROHM's official replacement guide for confirmed equivalents.
